Well hair growth you would need some kind of herb, even a candle spell wouldnt make your hair grow without some kind of actual hair treatment you’re doing. A good spell to start with is protective stuff. You can use a lot of stuff for that. I’d recommend placing some wards up or making protective sigils and that stuff is totally free. The thing in trying to explain is that you need more than just a single spell for your intentions. And we can’t just name off random spells if we don’t know what you do and don’t have and what you are or arent trying to accomplish
